Mile,

You're close! This one is easy to get confused on, based on how prompt() works, and on how the task is worded.

If you recall, whatever a user enters into the prompt when it pops up is the value that will be stored in the variable that the prompt is assigned to, so you actually need to write less than what you've got!

You need to create a variable called 'answer', and assign the prompt to that variable, so that the value given to the prompt will be stored in that variable.

var answer = prompt('What day is it?');

// to test this out and see the result, you can add this console.log statement, copy and paste all of this into your dev tools, and run it
console.log(answer);

Hope this helps to make a little bit more sense of things!

Oops, something was wrong. My first line - var day = prompt('What day is it?'); My second line - var answer = prompt('What day is it?');

And what's happened - I have two dialog box in row with question What day is it? But I don't need, I want to display answer as dialog box when I write a day.

Mile,

You only want the one line, not two. Writing the following takes care of everything for you:

var answer = prompt('What day is it?');

That line creates a variable in which the user's answer to your prompt will be stored. You do not need to create a second variable or a second prompt; that is the only thing you need.

The prompt function RETURNS the value the user types in to the prompt. So to store the the users response in the answer variable, switch day with answer like so:

var answer = prompt('What day is it?');

Challenge 3 of 3 Use the document.write() method to write the variable answer to the page.

var answer = prompt('What day is it?'); //This will get the answer

//then to display the answer
document.write(answer);

you do not need the day variable at all, since answer is what is holding the day

If you need to then use the document.write() method to write the variable answer to the page, do just that! Beneath your prompt line in your code, call document.write() and pass in the "answer" variable as the parameter for the method.

I kept coding like

var answer = "What day is it?"; prompt("What day is it");

I think your answer is fine, the problem with treehouse is they want strings to be exactly the same. Make the 'w' in 'what' a capital and it should be good.
